在炮弹弹体锻造过程中,加热钢坯是弹体制造中耗能最多的一道工序。为了节能以降低弹体制造成本,美国陆军军械研究与发展司令部弹药系统局研究了降低弹体锻造温度的方法。研究试验是以155毫米M107弹体为对象,并在斯克兰顿陆军弹药厂进行。该弹体的现行锻造工艺是以1204℃炉温将锻造用钢坯加热到1093℃。该厂有六座转底炉,炉温为1204℃时每座炉子的天然气耗费量为609立方米/小时。加热炉的设计能力每小时可将180个重50公斤
In the shell projectile forging process, heating the billet is the most energy-consuming manufacturing process in a body. To save energy and reduce the cost of projectile manufacturing, the Ammunition Systems Administration of the Army’s Ordnance Research and Development Command studied ways to reduce the temperature of projectile forging. Research trials are based on the 155 mm M107 projectile and are carried out at the Scranton Army Ammunition. The current forging process of the projectile heats the forging billet to 1093 ° C at a temperature of 1204 ° C. The plant has six rotary hearth furnace, the furnace temperature of 1204 ℃ when the gas consumption per furnace is 609 cubic meters / hour. Heating furnace design capacity of 180 can weigh 50 kilograms per hour
